If you invest $500 per month for 40 years and get 6% interest, you'll end up with almost a million dollars.

$6,000 per year is a significant portion of your take-home income if you're making the median income in the US, but it's possible.

Having $1M (or even $2M or $3M) 40 years in the future is not FU money. Not to mention that if you are unemployable anyway due to old age, you do not need to say FU to anyone in the first place.

There is no set amount you need to make or save. The goal is to learn what you don't need. One of the things you don't need is to say FU.

The thread stems from onion2k’s claim that a regular job will never get you to “FU money”.
